Abstract

The invention discloses a novel pogo pin. The novel pogo pin comprises multiple insulated and concentric contact needles. Each contact needle corresponds to a needle tube matched with the contact needle, a tension spring is connected between each contact needle and the needle tube corresponding to the contact needle, and each contact needle can move in a telescopic mode in the axial direction of the corresponding needle tube. The needle tube corresponding to each contact needle is fixedly and electrically connected with a corresponding circuit, and each contact needle is elastically connected with a corresponding conductive terminal. By the adoption of the scheme, the contact needles can move in the telescopic mode along the corresponding needle tubes, it can be guaranteed that the contact needles stably make contact with contacts in the using process, and open circuits are avoided. It can be guaranteed that first contact needles and the second contact needles are independently separated through insulating bushes, and short circuits are avoided. Each contact needle is of a columnar boss structure with the front portion narrower than the rear portion, the contact needles and the needle tubes are easy to install in the assembly process, production efficiency is high, and no additional buckle structure is needed for fixation.

Description

technical field [0001] The invention relates to a manufacturing process of a spring probe, in particular to a novel spring probe. Background technique [0002] Spring probe, also known as Pogo pin, also known as antenna thimble, probe, and thimble, is a precision connector used in mobile phones and other electronic products. It is widely used between mobile phone antennas, mobile phone batteries, etc., and mobile phone motherboards The connection function is to solve the purpose of connection that cannot be completed with shrapnel or other connectors for customers. Pogo pin has stable performance during use, high contact performance, and wide range of connection uses. It is the first choice for connectors. There is a precision tension spring structure inside the pogo pin. The Pogo pin consists of three parts, the needle, the tension spring, and the needle tube. [0003] Existing multi-pole interfaces are usually connected by cards and the pole piece is usually a fixed con...
